Need advice

I'm 21 weeks and I found out last Tuesday that I'm having A Boy 😊💙 . That next hour , I found out that the father of my child has another baby on the way . The baby is due 3 months after I have my baby . I didn't think my first pregnancy would go like this . I have good days majority of the time then some days I'm just hurt by all this . He's never there for my son and I. I just didn't want my son growing up the way I did , and from the looks of it he will be .
